Lawn Mower Filters
There are three lawn mower filters that you need to be aware of: air filters, fuel filters, and oil filters.
1. Air Filters.
Air filters must completely strain dust and dirt to protect the engine. It must also deliver a full volume of clean air to ensure correct carburetion. A clogged filter raises engine temperature.
Clean after every 25 hours. It must be done more frequently under dry and dusty conditions.
- Remove the knob and cover.
- Remove the surrounding spongy pre-cleaner from the air filter.
- Clean the dry components by tapping gently.
- Wash the pre-cleaner with soap and water. Dry thoroughly. Or blow out using compressed air.
- Replace if very worn, dirty, or oily. Use factory specified part number to replace air filters.
- Check carburetor.
2. Fuel Filter.
- Change fuel filter annually.
- Make sure the engine is stopped and cooled down. Spillage could occur. Gas is very flammable.
- Turn the fuel shutoff knob so that the points on the knob are facing away from the carburetor to the closed position.
- Remove the fuel filter from the fuel lines.
- Replace the fuel filter from the fuel lines. Use the original fuel filter when possible.
- Install fuel lines on the fuel filter.
- Fasten with clamps.
3. Oil Filter
- Change oil filter after 100 hours of use or annually, whichever comes first.
- Turn the oil filter counterclockwise and remove it.
- Apply a thin film of clean oil on the new filter’s seal.
- Install the new filter by turning until the seal contacts the mounting surface.
- Turn by hand ½ turn.
- Run the engine at slow speed for 2 minutes.
- Check for any leaks around the filter.
- Check the oil level.
- Add oil only to the full mark on the dipstick.
- Install and tighten dipstick.
